Platform, device version and operating system:
What you were expecting to happen, and what actually happened:
After starting a Gnome-a-palooza, a solid white rectangle appeared in the middle of the screen. It covered approximately two gems wide by three gems high. This persisted through the entire GAP and went away when I restarted the game.
How often does this happen? When did it begin happening?
So far seems like a one-off
Steps to make it happen again
Not sure. I don’t know if the GAP was related or if it was random coincidence. But definitely something went really, really wrong.
